Login to ssh and enter:

Block ip (aaa.bbb.ccc.ddd is IP):
iptables -A INPUT -s aaa.bbb.ccc.ddd -j DROP
service iptables save

View iptables:
vi /etc/sysconfig/iptables

Locking ports:
iptables -I INPUT -p tcp --dport 21 -j DROP
iptables -I INPUT -p tcp --dport 443 -j DROP
iptables -I INPUT -p tcp --dport 25 -j DROP
iptables -I INPUT -p tcp --dport 143 -j DROP
iptables -I INPUT -p tcp --dport 110 -j DROP
iptables -I INPUT -p tcp --dport 22 -j DROP
iptables -I INPUT -p tcp --dport 3306 -j DROP
iptables -I INPUT -p tcp --dport 7777 -j DROP
iptables -I INPUT -p tcp --dport 7778 -j DROP
iptables -I INPUT -p tcp --dport 6666 -j DROP
iptables -I INPUT -s aaa.bbb.ccc.ddd -p tcp --dport 21 -j ACCEPT
iptables -I INPUT -s aaa.bbb.ccc.ddd -p tcp --dport 3306 -j ACCEPT
iptables -I INPUT -s aaa.bbb.ccc.ddd -p tcp --dport 110 -j ACCEPT
iptables -I INPUT -s aaa.bbb.ccc.ddd -p tcp --dport 25 -j ACCEPT
iptables -I INPUT -s aaa.bbb.ccc.ddd -p tcp --dport 7777 -j ACCEPT
iptables -I INPUT -s aaa.bbb.ccc.ddd -p tcp --dport 7778 -j ACCEPT
iptables -I INPUT -s aaa.bbb.ccc.ddd -p tcp --dport 6666 -j ACCEPT

Where aaa.bbb.ccc.ddd is your IP address from which you are connecting to server.
Important! After rebooting your server, you need to setup iptables rules again.
